TPA3110D2 15-W Fil ter-Free Stereo Class-D Audio
Power Amplifier With Speakerguard™ 数据表 
TPA3110D2是一款15 W（每声道）高效的D类音频功率放大器，用于驱动桥接式立体声扬声器。先进的EMI抑制技术可在输出端使用昂贵的铁氧体磁珠滤波器，同时满足EMC要求。 SpeakerGuard™扬声器保护电路包括可调节功率限制器和直流检测电路。可调节功率限制器允许用户设置低于芯片电源的“虚拟”电压轨，以限制通过扬声器的电流量。直流检测电路测量PWM信号的频率和幅度，如果输入电容损坏或输入短路，则关闭输出级。
TPA3110D2可以驱动低至4Ω的立体声扬声器。 TPA3110D2的高效率（90％）在播放音乐时无需外部散热器。
输出也可完全防止GND，VCC和输出到输出的短路。 - 电路保护和热保护包括自动恢复功能。
